What are you?
You're a writer. Even if your books have not been published. Or if they have. Or if there is more than one. You may have won an award (congrats!). You may be agented, not-agented, soon-to-be-separated from the agent from Hell.
But: you're a writer.
That's all you need to tell me, and you don't need to tell me even that. Let your writing show me you're a talented and amazing writer. Show me. Don't tell me.
I'm cantankerous, sardonic and perpetually annoyed enough at this stage of my career that I don't believe anything anyone tells me.
"I was nominated for an Edgar" means I look up the Edgar list for that year.
"I have been published before" means I look you up on Amazon.
"My agent slithers" means I call up Barbara Poelle and ask why she's letting you go.
All you need to do is tell me about a novel I want to read. And I'll read it. Have confidence enough to let your writing speak for itself. You're a writer. I'm a reader. That's all we know, and all we need to know (sorry Keats, couldn't resist.)
